摘要： A bolt assembly of a gun includes a bolt body displaceable along a longitudinal axis, a firing pin guided to move axially in the bolt body, a firing pin spring associated with the firing pin, and a small breech arranged at the rear end of the bolt body. A sliding sleeve actuatable by a cocking slide is arranged to cock and uncock the firing pin spring. The cocking slide contains a control cam for axial displacement of the sliding sleeve by a slide part that can be moved in a straight line in the direction of longitudinal axis of bolt body and projecting rearward relative to the small breech.

摘要： Retaining devices securable on firearms are selectively operable to engage and retain a bolt assembly in a substantially-fixed position for an indeterminate period of time. The retaining devices include a mounting plate securable to the receiver and a retention pin that extends through a passage in the mounting plate. The retention pin extends axially between first and second ends that project outwardly beyond the mounting plate. The retention pin is supported on the mounting plate for axial displacement between a first pin position and a second pin position. In the first pin position, the second end of the retention pin engages and retains the bolt assembly in a substantially-fixed position relative to the receiver. In the second pin position, the second end of the retention pin is disengaged from the bolt assembly.

摘要： One example control element for controlling a breechblock stop lever that can move about a first axis of rotation, which can be moved between a standby position for releasing a breechblock carrier and a retaining position for retaining the breechblock carrier, includes a first arm (15) that can rotate about a second axis of rotation (B), a first control section on the first arm, the first control section including a first contact surface (11a) and a second contact surface (11b) facing away from the first contact surface (11a), which can be rotated about the second axis of rotation (B) for the control element (10) by a control curve (36, 37, 38) on the breechblock carrier (30); and a second control section (13) on the first arm, wherein the second control section can be controlled by a control surface (55a) on a trigger (50). Other examples are possible.

摘要： A device implementable on a firearm includes a main body and a paddle portion. The main body includes a bolt catching portion, a first protrusion, a second protrusion, and a pivot portion connecting the bolt catching portion, the first protrusion and the second protrusion. The paddle portion is detachably attached to the first protrusion and the second protrusion of the main body. The paddle portion includes a first paddle, a second paddle, and a connecting portion connecting the first paddle and the second paddle. The pivot portion is pivotably coupled to the wall to allow the bolt catching portion to pivot between a bolt releasing position and a bolt stopping position. The first paddle is coupled to the first protrusion and the second paddle is coupled to the second protrusion.

摘要： A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.

摘要： The present disclosure generally relates to a bolt catch device that prevents the bolt of a bolt carrier assembly of a firearm from moving to its forward position so as to prevent the firearm from being discharged until the user manually moves the bolt catch. The bolt catch is mechanically coupled to the selector of the firearm via a linkage, so that the bolt catch can be moved by way of the selector. This feature can prevent a self-loading firearm that otherwise could function on a semi-automatic basis from operating in such a manner.

摘要： A firearm has a first side, a second side, a forward section with a barrel, and a rearward section with a stock. The firearm has a central section with an actuation button on the first side and a bolt catch and bolt catch linkage on the second side. A magazine and magazine release are between the actuation button and the bolt catch linkage. An actuation pin extends through the central section from the actuation button to both the bolt catch linkage and the magazine release. A coil spring urges the actuation button outwardly to an inoperative extended orientation. The actuation button is adapted to be depressed for both releasing the magazine and engaging the bolt catch.
